Improvement in galvanic batteries



iM PiiovE'MEiNi" iN GALVAN i o` BA Speeiication forming'lpart of LettersPatent No. 6,862, dated April, 17, 1849.

To all 'whom it may coiwern:

Beit known that 1, ADoLPHUs tlLrrsrnnn, of the borough of Easton, in thecountfyof Northampton and State of Pennsylvania, have invented a new unduseful improvement in'the hydro galvnnic electro magnetic instrument formedici nahchcmical, philosophical, mechanical, and other purposes,`called Olnisteads Improved Voltaie Arrangement, which iede- Yscribed asfollows, reference being had tothe annexed drawings of the saine,nia-king part of jthis speciiicnton.

Figure l is a perspective View of the apparatus as arranged foroperation. `Side elevation of the shield, plates, studs, pins,- Fig. Ilis one of the copper pins detached from its circle. Fig. 5 is one of thezine pins, also detached from its circle. Fie'. (3 is a plan or top Viewof the galvanic battery. Fig. 7 is' an inverted view of the saine.

Similar letters in the several figures refer to corresponding parts.,

rihe nature of my invention and improveuufut consists in forming agalvanic battery of concentric plates or rings U U', containing,ri-,opper' and zinc pins or plates, said rings U U being of similar ordissimilar metals7 arranged in. alternate order and united by.' wiresVr', This galranic battery is placed in a stutionnri;l cell, t), orreservoir, of glass oriother suits-b c material, and is connected to anelectromagnetic battery, l1, by conductingarires l, in the usual way.The wheel H of the electro-magnetic battery is turned by mechanicalineens linstead oit' by hand.

.'Lhc mechanism I generally employ consists etang of the known powersot' motion, such asa coiicd spring arranged in the box .or eylindriealcase K2, and cogged wheels L orweights, etc., driving atrain ot wheelsconi-iected to a pinion, lll, on the shal't'N of thiir electro-magneticwheel Il.

The galraniebatteryfor producing roltaic electricity for medical andother purposes is constructed of a series of perforated concentriemetallic rings, U U', connected together by coiilucting-wires YV, saidrings being ai'.- tuoheti by screws or other means to a perlorated coveror shield of wood, Y, which is placed over the top ol' a gah-anictrough, t), containing;diluted sulphuric ncid, through which cover andrin are introduced coppe and zinc plates or pins, solid or tubular,forin; ingr a powerful battery, involving in its own formation a naturaland perfect mode of graduation, giving at all times the' operator thelmost entire control over the quantity of its ininence by the addition orsubtraction of the aforesaid pins or plates. l

V 1s the shield; U Uf, the concentric rings screwed to the shield; il",the cond noting-wires; for connecting the brass rings, as represented inthe drawings; T T', the coppernnd zine pins; l I, the conducting-wiresfor connecting fthe galvanie battery with the magnetic bat tort rlhegalranie battery nia-y also be formedl'of perforated metallic bars 'ofsimilar or dissimilar metals, connected alternately by wires,,as abovedescribed, through which copper and rinoV plates or plus, solid ortubular, niej* be introduced to form the battery on tlie'sauie principlens above stated, the pins or plates being increased in numberto-strengthenand diminished to reduce the batter? Operation: Adjust thecover i rshield-ovcr the top of a gnlvan ie trough containingr dilutedsulphurio acid or other veorroding liquid, the surface of the solutionbeing` about half iin-inch from the underside ol' the perforated pia-tesattached to the shield, and the perforated plates being,` conn eted byconducting-wires to the magnetic battery, and the instrument otherwiseproperly adjusted, thel operator will introduce through the apertures inthe rings or bars copper and zine pins or plates, forming a singleroltnie pair in notion. ll' the nc -tion. be snliicient, the operatorwill proceed;

but it' too leeble another pair must be introduced, and so on until asuilicient action be obtained to produce the desir -d elle: 1i' found toact too powerful, it un st by withdrawing the pins or plates battery,which rires the operalor at all times complete control over the urti-onci' the inslruf nient, and doesaway with the ordinary modes ofgraduating' the batteryV by raisin and low` ering the plates orelevating und depressing the acid solution in which the plates are inwiuersed. y
